Cataulacus guineensis

Quick Summary

• Difficulty: Medium
• Origin & Habitat: West Africa and Congo Basin, found in forests nesting in rotten branches high above ground, often on trees like cocoa ^[1].
• Colony Type: Unconfirmed, queen number not specified in research literature.
• Size & Growth:
  • Queen: 7.7-9.5 mm ^[1]
  • Worker: 4.5-8.6 mm ^[1]
  • Colony: Up to several hundred workers ^[1]
  • Growth: Moderate, estimated based on tropical arboreal ant patterns
  • Development: Estimated 5-8 weeks at tropical temperatures (25-28°C) (Development speed depends on temperature and feeding)
• Antkeeping:
  • Temperature: Keep at 24-28°C. As a tropical species, they need warm conditions year-round.
  • Humidity: Keep nest substrate consistently moist but not waterlogged, with good ventilation.
  • Diapause: No, tropical species do not require hibernation ^[1].
  • Nesting: Arboreal nesting in Y-tong or plaster nests with narrow chambers and climbing structures like twigs or cork bark ^[1].
• Behavior: Cataulacus guineensis is calm and non-aggressive. Workers are subordinate at food baits and avoid conflict with dominant ants like Oecophylla longinoda ^[3]. Their primary defense is passive, relying on their hard exoskeleton, and they will roll and drop to escape when threatened ^[2]. They are handleable but require secure enclosures to prevent escape.
• Common Issues: tropical temperature requirements mean colonies struggle in cool rooms, monitor with a thermometer., arboreal nature requires vertical space and climbing structures, not just horizontal floor space., as honeydew farmers, they may ignore sugar water if not hungry, offer protein regularly., size variation in workers is normal and not a sign of health issues., sensitive to insecticide exposure, never keep near treated areas.

Housing and Nest Setup

Since Cataulacus guineensis is arboreal, your setup should reflect their tree-dwelling lifestyle. Use a Y-tong or plaster nest with chambers sized for workers 4.5-8.6 mm. Include vertical climbing structures like twigs or cork bark in the outworld. A test tube can work for founding, but upgrade to a larger nest once the colony reaches 20-30 workers. Ensure all connections are secure to prevent escape ^[1].

Feeding and Diet

In the wild, they tend aphids and coccids for honeydew. In captivity, offer sugar water or honey water constantly, plus small protein like fruit flies or mealworms 2-3 times weekly. They are not aggressive predators and prefer sweet liquids ^[1].

Temperature and Humidity

Keep temperatures at 24-28°C using a heating mat if needed. Create a gentle gradient for self-regulation. Maintain humidity by keeping the nest substrate damp but not waterlogged, with good ventilation to prevent mold. No diapause is required ^[1].

Behavior and Handling

Workers are calm and subordinate, avoiding conflict with dominant ants ^[3]. Their defensive rolling and gliding behavior means they may drop from surfaces if handled roughly ^[2]. They are not aggressive and pose no danger, but secure enclosures are essential to prevent escape.

Colony Development

Colonies grow to several hundred workers with notable size variation among workers ^[1]. Founding behavior is unconfirmed, but development from egg to worker is estimated at 5-8 weeks in warm conditions. Colonies are long-lived with proper care.
